Abstract: Eine Schaltung zum Nachladen des Ausgangsknotens (A) einer Feldeffekt-Transistorschaltung enthält einen Feldeffekt-Transistor (1), der über einen Kondensator (C1) periodisch leitend gemacht wird. Dadurch wird die am Ausgangsknoten (A) der Feldeffekt-Transistorschaltung vorhandene Kapazität (CE) periodisch über den positiven Pol (VH) der Versorgungsspannung nachgeladen. Das erstmalige Aufladen dieser Kapazität (CE) erfolgt durch einen kräftigen Impuls der Feldeffekt-Transistorschaltung, die eine Treiberschaltung (TR) ist. Um bei niedrigem Ausgangspotential der Feldeffekt-Transistorschaltung einen Stromfluß durch den Feldeffekt-Transistor (1) und damit das Erzeugen einer Verlustleistung zu verhindern, ist der Feldeffekt-Transistor (2) vorgesehen. Seine Gate-Elektrode ist mit dem positiven Pol (VH) der Versorgungsspannung verbunden. Der Feldeffekt-Transistor (2) ist daher bei niedrigem Potential am Ausgangsknoten (A) leitend und überträgt dieses Potential zur Gate-Elektrode des Feldeffekt-Transistors (1). Dieser leitet dadurch nicht, weil seine Gate-Source-Spannung kleiner als die Schwellwertspannung ist.

Abstract: A pulse generating circuit (12) generates two current pulses (d and e) which immediately follow one another. The amplitude and duration of the first current pulse (d) are sufficient for attracting the armature of the electromagnet (21), the amplitude of the second current pulse (e) is only sufficient for holding the attracted armature and its pulse duration corresponds to a predetermined period during which the armature is to be held in the attracted position. A feed circuit (1, 2) fed from the subscriber line (3) supplies two voltages of different magnitudes, the higher voltage being applied to a switching transistor (31) of the section (11) of the pulse generating circuit (12) switching the first current pulse (d) and the lower voltage, which is a fraction of the higher voltage, being applied to a switching transistor (14) of the section (15) of the pulse generating circuit (12) switching the second current pulse (e). As a result, the electromagnet (21) can be fed with minimum power consumption from the subscriber line. <IMAGE>

Abstract: A method of separating isotopes of an element, for example uranium, comprises providing molecules of a compound of the element having an isotopically shifted, but overlapping, infrared absorption spectrum associated with the isotopes of the element which does not change appreciably on absorption of photons.

The molecules are irradiated at an infrared absorption frequency to isotopically selectively dissociate said molecules to provide molecular fragments over a time interval, and collecting only those fragments which dissociate within a predetermined portion of the time interval,for example between 0.1 and 10 microseconds after initiation of irradiation. Collection can comprise a second irradiation shifted by upto 100cm -1  and of pulsewidth less than 5 microseconds.

Filed: 1980-08-20
Abstract: A material and a process for use in making electrical contacts. The material is produced in powder form suitable for later processing into electrical contacts by standard metallurgical techniques generally involving compacting the powdered material to form a compact that preferably has a backing of metallic silver, sintering the compact to form the contact having a fine sintered silver backing and forming or cutting the contact to make it to the desired shape and size. The material, and in most general applications the contact made from the material, essentially consists of silver, approximately 15% cadmium oxide by weight, and lithium carbonate at a proportion of about .005 weight percent of lithium, which is approximately equal to .04 molecular percent of lithium carbonate. The lithium carbonate is added to the powder mixture of silver and cadmium oxide powder mixture as a solution which is thoroughly mixed with the powders to form a slurry to uniformly distribute the lithium carbonate on the surfaces of the powder particles of cadmium oxide and silver by precipitation. The slurry is then dried and precipitated material is pulverized and formed into a compact without reducing the lithium carbonate prior to sintering of the compact. Thus by using lithium carbonate instead of lithium nitrate as known in the prior art, the step of reducing the lithium nitrate to lithium oxide prior to sintering the contact material is eliminated without sacrificing the performance of the contact material.
